The Blanchardstown RDS. project will increase capacity of the sewerage networks to facilitate population growth and cater for increased flows because of Development Plans within the 9C catchment (including Fingal, Meath and Kildare areas). The design philosophy for the 9C Duplication and Storage is to duplicate the 9C for approximately 3.2km from Parslickstown Bridge to off-line storage tanks (approximately 30,000m3) in Waterville Park, adjacent to Mill Road. The tank configuration is currently proposed as comprising three underground storage tanks, with approximate dimensions of 30 metre internal diameter and depths ranging 2530m. EMCA are supplying the required electrical works to assist with site set up and construction works.
